Abstract: PURPOSE:To reduce the error caused by a capacity error of a capacitor, by replacing the two capacitors that distribute the electric charge into 1/2 for weighting to carry out the D/A conversion twice and then averaging the output of conversion. CONSTITUTION:The charge is carried out by closing the switch 3 for a fixed time when the LSB is ''1'' and after discharging the capacitors 1 and 2 by turning on the switches 4 and 6. Then the switch 5 is closed for a fixed time, and the electric charge is distributed by 1/2. The switch 4 closes for a fixed time when the next bit is ''0'' to reduce the electric charge of the capacitor 1 down to 1/2. The same procedure is given up to the MSB, and then the switch 8 is closed to hold the conversion output by the sample holder 9. After this, the switch 7a is switched to replace the capacitors 1 and 2 and thus carry out the same conversion. Then the switches 10 and 5 are closed to average the twice conversion outputs.

Abstract: PURPOSE:To obtain a thermal recording material having excellent image reliability (water resistance, chemical resistance, and oil resistance) by providing a protective layer comprising an aqueous ammonia solution of zinc oxide and an aziridine compound, on a thermal color forming layer. CONSTITUTION:Both an aqueous ammonia solution of zinc oxide and an aziridine compound function as water resistance imparting agents (cross-linking agents), but satisfactory image reliability can be obtained only by providing a protective layer comprising both of the two. The aziridine compound may be, for example, tetramethylolmethane tri-beta-aziridinylpropionate. A resin used as a main constituent of the protective layer may be, for example, a water-soluble resin such as polyvinyl alcohol. Further, auxiliary additives such as a filler, a heat-fusible substance (or lubricant) and a surface active agent may be incorporated in the protective layer, as required. Thus, a thermal recording material is obtained which is free of decoloration of image areas, even upon contact with oil, water or the like, and has a markedly enhanced reliability.

Abstract: PROBLEM TO BE SOLVED: To automatically conduct, with less risk, the cooling gas replacement work by controlling an automatic valve depending on the signal from a detector for detecting gas pressure and concentration. SOLUTION: When operation of an rotary electric machine 23 stops and a gas substitution start signal is input to a control panel 15, the hydrogen gas supply valve 1 closes and a bypass valve 2, a substitution control valve 5 and an air release valve 7 open to release the internal hydrogen gas to the open air. Here, the gas pressure is detected with a pressure detector 13 and when it becomes lower than the predetermined value, the carbon dioxide gas enters from a carbon dioxide gas unit 22 to push out the hydrogen gas to the open air. However, since the hydrogen concentration is always monitored with a gas concentration detector 16 and when it becomes lower than the predetermined value or less, substitution of hydrogen gas with the carbon dioxide gas is completed.  Next, when a high pressure air is supplied from an air supply unit 14 to release the carbon dioxide gas to the open air but the carbon dioxide gas concentration is monitored with a gas concentration detector 16 and when it becomes sufficiently low, such release is completed. Thereby, substitution of hydrogen gas may be done automatically with less risk.
